factor 4a-20+5a^2-a^3

factor

4 a - 20 + 5 a^{2} - a^{3}

- (a - 5) (a + 2) (a - 2)

Solution steps

4 a - 20 + 5 a^{2} - a^{3}

Write in the standard form

= - a^{3} + 5 a^{2} + 4 a - 20

Factor out

- 1 : - (a^{3} - 5 a^{2} - 4 a + 20)

= - (a^{3} - 5 a^{2} - 4 a + 20)

Factor

a^{3} - 5 a^{2} - 4 a + 20 : (a - 5) (a + 2) (a - 2)

= - (a - 5) (a + 2) (a - 2)

(- x^{2} + 9) + (- 3 x^{2} - 11 x + 4)

\frac{z}{z ^{3} z ^{- \frac{1}{2}}}

x y + x y - y x

(a^{16})^{\frac{3}{4}}

2^{3^{4}}
